1. Fifteen years of census data from a population of the red harvester ant (Pogonomyrmex barbatus), 5 years of census data from populations of Aphaenogaster cockerelli and Myrmecocystus mimicus at the same site, and longterm precipitation data from a nearby weather station were used to examine how nearest interspecific neighbours, climate, and life history influence P. barbatus colony mortality...

The aim of this study was to provide practitioners working with trawl selectivity with general and easily understandable guidelines regarding the fish sampling effort necessary during sea trials. In particular, we focused on how many fish would need to be caught and length measured in a trawl haul in order to assess the selectivity parameters of the trawl at a designated uncertainty level. We a...

Although goatfishes (Mullidae Rafinesque, 1815) are among the most important commercial fishes in Turkey, no research has been found investigating characteristics and spatial patterns of goatfish fishery. Here, we assessed fishery Turkey based on microdata set Turkish National Fishery Statistics gathered by Statistical Institute (TÜİK) between 2014 2017. In this context, investigated variation ...

Discards represent a loss of natural resources and negatively affect the sustainability fisheries. Information on discards, such as diversity size species discarded is essential to better manage trawl Thus, this study aims gain knowledge discards from Catalan bottom fisheries in NW Mediterranean Sea offer information needed for management. Discard ratios, composition lengths were analyzed data ...

A new goby species Tridentiger radiatus sp. nov. is described from Zhuhai, Guangdong Province of China. The new species, found in sympatry with a widely distributed barbeled congener Tridentiger barbatus (Günther, 1861), is one of the only two Tridentiger species known to possess mandibular and cheek barbels. Tridentiger radiatus is diagnosed by having higher longitudinal and transverse scale c...

Clearance rates, respiration rates and food absorption efficiencies of the commercially interesting subtidal bivalve Modiolus barbatus were measured at different temperatures under laboratory conditions and scope for growth calculated. Clearance rates were highest at temperatures from 20 °C to 28 °C, whereas respiration rate was maximal at 9 °C and minimal at 26 °C. Highest mean values of absor...
